To all whom it may concern:

Be it known that I, FERDINAND DAssY, a

dent of Rouen, France, have invented new, and useful Improvements in or Relating to l the Removal of Household or other Refuse, 1 which improvements are fully set forth inf the following specification.

This invention relates to apparatus byl means of which household or other refusej can be collected in a closed vessel and the boxes or dust bins emptied without coming into contact with the outer air, so that any, smells and dust are thus prevented.

This machine also makes possible, by a; suitable arrangement the removal of refuse which has been placed in a heap, such as the waste and litter from the markets, sweepings from the streets etc.

The apparatus in which is used either; compressed air, for collecting refuse in boxes, 1 or rarefied air or a vacuum, for removing; the refuse in heaps, can, therefore, havei difi'erent constructions, not only according: as to whether it is to be used for removal of l refuse in boxes, or for removal of refuse placed in heaps, but also accordin as the power required for removing the refuse contained in the boxes, is produced by an air. compressor driven by a motor, or the said; power stored in a tank or tanks (compressed f air at the pressure required).

Two constructions of the apparatus ac cording to this invention are illustrated by way of example in the accompanying dravving in which Figure 1 is a side elevation showing thej machine chiefly intended for collecting refuse contained in boxes or dust bins, Fig. 2 is a side elevation of the apparatus arranged for the removal of refuse placed in heapsf and, Fig. 3 is a vertical cross-section of the 1 construction shown in Fig. 2. Fig. 4 is sectional View, on an enlarged scale, of parts j of the machine shown in Fig. 1. Figs. 5 and 6 are detailed views of a stuffing box hereinafter described, Fig. 7 is a fragmentary? plan view of the hinged floor hereinafter referred to, and Fig. 8 is a detailed iew of a spring catch hereinafter described.

In the construction shown in Fig. l, the, apparatus comprises a metal case 1 of suitable capacity, the bottom 2 of which is, inclined forward. In front there are an,

; ranged two compartments 2 to which are secured two metal tubes 3. The width of the tubes 3 gradually decreases while renaining sufficient for the passage of waste or litter of any kind, contained in the boxes or dust bins' These tubes or pipes which are preferably inclined at an angle of 2530,

I are provided with a depression at 4 and ,are continued up to the upper rear portion of the casing opposite a baffle plate or pro- ,tector 5. Two tanks 6 are arranged on the casing. They contain air compressed to a jhigh'pressure. At the moment of use, the

1 air in question passes through the pipes 7 which can be closed or opened by cocks 8, into a heater 9 of any desired construction, and afterward into a regulating reducing device 10, whence it escapes through the con- ,duits or pipes 11 at a pressure of about six atmospheres.

The heater is employed to raise the temperature of the air so as to counteract as far as possible the cooling which takes place upon the escape'and expansion thereof. The reducing valve 10 is provided for the purpose of insuring a substantially uniform pressure being delivered to the pipes 11 regardless of the pressure in the tank 6, which necessarily falls gradually as the air is used .11

The air sent into the casing, escapes again through a filter 12 constituted by metal netting alternating with felt layers, the whole being impregnated with deodorizing disinfectants.

Doors 13 and 13 with edges provided with rabbets or grooves packed with rubber, arranged at the back and at the sides, enable the apparatus to be emptied after the collection.

The whole apparatus is mounted on wheels.

The dust bins or boxes to be emptied, are introduced into one of the compartments 2 and placed on a floor 14 movable about hinges 15, where they are securely held by means of spring catches 16, as clearly shown in Fig. 4. The door 17 of the compartment 2 having been closed an attendant rotates the handle 18 a quarter of a revolution in the directon shown by the arrow 19. The floor 14 then pivots about its hinges and comes to rest against the edge 3, of the pipe '3, where it is held by spring latches 20. See

V steel.

' detach all the greasy and sticky material Figs. 4 and 8. The handle 18 is mounted on a spindle 21 secured to a lever 22 provided at its end with a roller 23 mounted in the rails 24. The box or dust bin 25 being at that moment in the position shown in chain dotted lines in Fig. 1, its contentsare discharged at 4. The attendant rotates to the extent of one revolution the handle 26 mounted on a spindle 27 provided with a certain number of tongues 28 of very flexible These tongues which are thin and very narrow adapt themselves to any irregularities which they meet in their travel and come to rest against the bottom of the box 25 where they act like a glaziers knife to adhering to the bottom of the box. The spindle 27 passes through stuffing boxes as shown in Figs. 5'and 6 so as to avoid leakage of air.

After the material has been discharged into the pipe 3, as described, the engineer,

having previously admitted a quantity of compressed air from the tanks 6 into the heater 9, allows the air in question to pass into the regulator 10 whence it passes into the pipes 11 terminating at different points of the pipe 3 in openings 11. Two further pipes 11 terminate in coils 29 where the air is given a helical movement owing to its passage through the said coils, and by the action of an agitator A arranged on the conduits 11. The household refuse is then carried. away by the said eddying air into the pipe 3 and discharged into the case 1. A protector device 5 faced with rubber or any other elastic material, protects the wall of the case against. any damage by the violent shocks of the refuse contained in the boxes 25. For insuring a tight joint of the pipe 3 when the floor 14 has closed its opening 3, the edges of the floor and of the pipe are provided with grooves or rabbets. For the same purpose, a semi-cylinder 30 of supple material having an accordion-plaited shape is secured both to the edge of-thepipe 3 and to the edge of the floor 14, so as to cover the hinges 15. Pipes ,11 having branches which terminate at the semi-cylinder 30, so as to free it from any dust that may ac- I cumulate therein, and insure the proper working of the hinges.

This is clearly shown in Figs. 4 and 7 The latches 20 are raised automatically when the floor 14 is ready to move into contact with the pipe 3. When the floor in question has arrived at the end of its travel,

they fall down, being actuated by springs. In order to raise the latches so as to enable the floor 14 to return to its original position,

. the said latches are connected by means of cables passing over guide pulleys, to a chain cable 31. Inthese conditions, by pulling on the cable 31 I sliding on the pulleys, the latches are raised, and the floor 14 then returns to its place as soon as the handle 18 is turned to a quarter of a revolution-in the direction opposite to that of the arrow 19. Handles 32 enable the door 17 to be raised, and its closing is insured by a bolt 33.

In the preceding description, the apparatus has been assumed to contain two compartments 2, two pipes 3, two compressed air tanks 6, etc, but it is obvious that it could also be equally well provided only with one compartment 2, one pipe 3, one compressed air tank 6 etc. The arrangement of the different parts could also be varied. The construction of the apparatus shown in Figs. 2 and 3, is chiefly intended for removing refuse which has been placed in heaps, such as for instance the street sweepings. This apparatus can also remove refuse contained in boxesor dust bins. It comprises a compartment 34 arranged in the interior of the case, and the said compartment is surmounted by a suction hose 36 through which is forced back the refuse expelled by the compressed air as already stated. Otherwise the compartment 34 is equipped with apparatus similar to that illustrated in connection with the compartment 2 in Figs. 1 and 4. A rubber hose 37 or a pipe made of other flexible material, of large diameter, is secured to the case 35 by means of a collar or flange 38. Being provided with a pivot joint at its point of attachment, the flexible conduit can, therefore, be inclined at any desired angle. A widened portion 39 provided at the free end, is intended to be placed over the refuse heap to be removed, and to form a suction mouthpiece or a sweep up. This widened portion or sweep up is made of rubber, the thickness, and consequently the strength, of which decreases toward the circumference, so that it adapts itself well to the shape of the pavements, or fills up the hollows and the holes in the ground to which, the said sweep up is applied. The vacuum in the case 35 is produced by means of a pump 40 connected to the said case by a conduit 41 terminatin at a bell 42 surmount'ing a filter 43 arrange at the upper portion of the case. The workman places the pipe on the heap of refuse to be removed and opens the cook 44 arranged on the flexible conduit 37 The refuse is forced by the air to rise in the pipe 37 and thence in the inner conduitv 45 at the end of which it is stopped by means of a hood 46, which forces it to fall back into the case. Any dust and ashes are stopped by the filter 43, and the air arrivin at the pump is thus almost pure. 7 I claim- 1. Apparatus for collecting refuse comprising a closed casing, a compressed air tank carried thereby, a conduit lying wholly within said casing, means for depositing; the waste material in the mouth of said conduit and means for discharging compressed air from said tank into said conduit adjacent such material, whereby the material is driven through the conduit into the casing.
